Patent GB-735714-A (GB)
Title: Concentrated ready-to-dye liquid reduced indophenol sulphurised vat dyestuffs
Inventor: ROBINSON EWEN DAVIDSON
Filed: 1952-10-06
Abstract: The invention comprises a concentrated filterable aqueous solution of a reduced indophenol sulphurized vat dyestuff containing a small but effective amount of a hydrotropic agent, the solution having a relatively high concentration of dyestuff and an improved stability against precipitation of the dyestuff or tar formation.  The presence of the hydrotropic agent allows of a relatively high caustic alkalinity, e.g. up to 2-4 per cent, without precipitation or tar formation.  Dyestuffs mentioned are obtained by thionation of carbazoleindophenol and N-(4-hydroxyphenyl) betanaphthylamine. Specified hydrotropic agents are sodium, potassium and ammonium salts of sulpho and carboxylic acids and their derivatives, e.g. phenyl acetic acid, o-toluic acid, xylene sulphonic acid, cymene sulphonic acid, p-toluene sulphonic acid, naphthalene sulphonic acid, metanilic acid, sulphanilic acid, tetrahydronaphthalene beta sulphonic and carboxylic acids, N-benzyl sulphanilic acid and N,N-dibenzyl sulphanilic acid.  Sulpho-betaines are also mentioned as hydrotropic agents, sodium xylene sulphonate and p-toluene-sodium-sulphonate being preferred.  About 3-15 per cent based on weight of final solution of hydrotropic agent is used.  A mixture of such agents may be used.  The addition of water-soluble solvents may be an advantage, such solvents specified being glycerol, diethylene glycol, thiodiethylene glycol and glycol-ethers.  The concentrates may be made by adding the dyestuff press cake to a solution of the hydrotropic agent followed by reducing agents and alkalis.  In examples a thionation product of carbazole indophenol and a polysulphide is dissolved in water containing as hydrotropic agents: (1) sodium xylene sulphonate; (2) sodium p-toluenesulphonate; (3) sodium metanilate; (4) tetrahydronaphthalene sodium sulphonate; (5) urea; and (6) thiourea and a thionation product of 4-hydroxy-phenyl-beta-naphthylamine is dissolved in water containing (7) sodium sulphonate; (8) sodium p-toluenesulphonate; (9) hexamethylenetetramine; (10) sodium metanilate; (11) urea; and (12) thiourea, all solutions being finally reduced with sodium hydrosulphide.

Abstract: 1384151 Abstracting systems INTERNATIONAL BUSINESS MACHINES CORP 30 May 1972 [28 June 1971] 25164/72 Heading G4C Characters in predetermined positions in words of a record are encoded into one of a plurality of group codes and the number of times each group code is assigned to a record is counted to generate an abstract which is recorded in a tag portion of the record and subsequently used for information retrieval. As described the first and third letters of each word of a record on a magnetic card are sensed and assigned to one of three groups A, B, C the number of characters that fall into each group being counted to generate two 7-bit binary words, the sixth bit of each word being a "1" and four bits being assigned to each group. Using a 7-bit alpha numeric code the two corresponding characters are then recorded in the appropriate positions on the first track of the card. If however a record contains more than 15 characters in any group the capacity of the scheme is exceeded and a "forced search" character is recorded. If the record is on more than one track of the card the two characters are recorded in the appropriate position of the first track of the record the remaining character positions in track 1 corresponding to the remaining tracks being filled with "track skip" codes. To initiate a search an enquiry is typed and an abstract is generated from it. Record abstracts for which each group count exceeds the corresponding count for the enquiry abstract are compared with the enquiry, all records having "forced search" code abstracts being also compared. When a match is found the recorded information is typed out. If a record card does not have abstracts the enquiry and record words are compared character by character and an abstract is generated for each record on the card. The generated abstracts are stored and recorded on track 1 after the last record on a card has been examined. Magnetic tape may be used instead of magnetic cards.

Title: Keyboard Mechanisms
IPC: H01H13/70
Filed: 1968-05-27
Abstract: 1,169,833. Selective signalling. NATIONAL CASH REGISTER CO. 27 May, 1968 [15 June, 1967], No. 25219/68. Heading G4H. In addition to actuating a coded combination of contacts upon depression of a key, a keyboard is characterized in that upon further pressure on the key a switching device, common to all the keys, is actuated which device can be used to gate signals from the coded contacts to a transmission line, the resulting short delay being sufficient to allow any contact bounce to die away. A detailed mechanism employing conventional techniques is described. Each key is associated with a code-bar which when depressed engages with a corresponding combination of seven transverse switching rails, each of which, when actuated is arranged to interpose an extension thereof between a magnet and a reed switch unit, thereby causing the contacts to open. Further movement of a key is against an additional spring which becomes effective at about the instant that the coded contacts are actuated, and eventually the common switching device is actuated.

Title: Improvements in or relating to spinners for the hubs of airscrews
IPC: B64C11/14
Filed: 1937-09-17
Abstract: 485,903. Air-screws. VEREINIGTE DEUTSCHE METALLWERKE AKT.-GES. Sept. 17, 1937, No. 25241. Convention date, May 22. [Class 114] In air-screws having one-piece nosings or spinners, the construction includes a flange at the front of the hub to which the spinner is locked, and a flange at the back into which the spinner is pushed and centered. The hub 1 carries a flanged disc 2 and it is provided with a registering rim 3 for an annular plate 4 within the front part of the spinner 5. The parts are locked together by a ring that is itself secured to the plate 4 with a limited degree of angular movement thereto and which passes over screws 7 that are carried in the other plate. Movement of the ring 6 is obtained by using the spanner 14 which takes an abutment against pins 16 and 17 and which engages a pin 18 on the ring. Engagement and disengagement of the spanner is only possible when the spinner is locked in position owing to the position of the set pin 19. The rear edge 11 of the spinner is supported in the rim 12 of a disc 13 on the back of the hub 1. In a modification, the locking ring is carried by a disc 20, and this is rotatable by engagement of pins 27 with an inclined slot 26 in a tube 21 which is normally held by the spring 28 in the locking position. When the rod 21 is pulled outwardly against the spring action, the plate 20 rotates and the spinner is detached. In another form, the slidable rod is provided with projections which engage castellations in the locking ring and which, when being entered into position, press back a spring-held plate which normally locks the locking ring itself. Specification 451,553 is referred to.

Title: Improvements in reel-slitting and rewinding machines
IPC: B65H18/26
Filed: 1949-10-04
Abstract: 666,448. Paper-slitting machines. JAGENBERG-WERKE AKT.-GES., and SCHNEIDER, M. Oct. 4, 1949, No. 25467/49. Class 31 (i). A reel-slitting and rewinding machine of the type provided with a pressure roller carried in a pivoted cutter head and acting upon the rewound reel is characterized in that the weight or pressure of the cutter head on the work is relieved and controlled by spring action. As shown in Fig. 2 a cutter 9, counter roller 10 and pressure roller 12 are mounted between side cheeks 5 pivoted to pedestals 4 on the frame of the machine. Compression springs 21 carried in sleeves 23 act on levers 27 and apply an upward force to the cheeks 5 so as to relieve the downward force, due to the weight of the cutter head, exerted by roller 12 on the rewound web 1. As the rewinding proceeds the diameter of the rewound reel increases and the cutter head pivots upwards, resulting in a decrease of downward pressure by the roller 12. At the same time levers 27 are lifted with the cutter-head and allow springs 23 to expand, thus decreasing the upward force applied by the springs to the cutter head. An arrangement is also described employing, in place of two compression springs, a single tension spring.

Filed: 1964-06-19
Abstract: 1,126,901. Wire ropes; making. BRITISH ROPES Ltd. 17 Sept., 1965 [19 June, 1964], No. 25575/64. Heading D1T. During the stranding of wires onto a wire core the back tension and torque in the core are continually measured and controlled, just before a layer of wires or strands is twisted thereon, to maintain said tension and torque at or near a desired value serving to prevent the resulting rope from having a tendancy to loosen.  The torque and back tension may be determined by passing the core past the wheel 8. Fig. 7, and onto the wheel 7, half-way round the wheel 7 and then back onto the wheel 8, half-way round the wheel 8 and then forward again to pass the wheel 7. The wheels 7, 8 have their axes slightly skewed so that the core may pass round around them as stated. The wheels 7 and 8 are keyed to shafts 32 supported in bearings 33, 34 and 35 which are upwardly urged by springs 36, 37, 38. Torque on the core tends to rotate the wheels 7, 8 about axes perpendicular to the axes of the shafts 32 and parallel with the path of the core and this tendancy is measured by a load cell 39, the readings from which may be so calibrated as to provide a direct reading of torque in the core. The bearings 33 and 34 are also longitudinally supported Fig. 6 (not shown) and one of the supporting links for each wheel contains a load cell 40 which absorbs and measures the tensional forces imparted by the core to the torque measuring wheel. The readings from the load cell 40 may be calibrated directly into back tension in the core.  The readings from the load cells 39 and load cells 40 provide the machine operator, or an automatically controlled arrangement, information on which the reel supplying the core may be suitably braked and a cradle carrying said reel can be rotated by a motor to give the necessary back twist to produce the desired torque. Adjustable disc brakes may be used to give the desired tension. Figs. 8 and 9 (not shown) illustrate a single wheel arrangement that can be substituted for the two wheels 7 and 8. Figure 10 (not shown) shows a shaping die 12 and a sizing roller 48 acting on the core, the die 12 and roller 48 being mounted on a pivoted platform supported by a load cell 51 giving a reading of tensional forces absorbed by the die and roller.
